This application filed November 80, 1931. Serial No. 577,982.

This invention relates to means whereby type characters may be secured on bars in such manner that no adjustment of said bars or type relative to the platen upon which the type is forced, is required, in the operation of the type writer, billing machine, or other construction of which said type and bars form elements.

Among the objects of the invention is to obtain mechanism by means of which a predetermined relative position of the type characters and the type bars of a type writer, billing machine, or the like, can be obtained, and said characters and bars rigidly joined in said determined relative position. An additional object is to obtain mechanism whereby type characters and corresponding type bars can be readily assembled in proper relative position and the rigid joining thereof be rapidly effected. An additional object is to obtain mechanism whereby type characters and corresponding type bars can be assembled and rigidly oined in such manner as to obviate any adjustment to align said characters relative to a platen, after the plate on which bars are mounted is secured in place on a type writer, billing machine, etc. An additional object is to obtain mechanism of the kind and for the purpose set forth which is simple in construction, durable, not liable to become broken or to get out of order, and which is easily operated by a person of moderate skill in the art.

between which, also, said end of the bar and said type character extend when the type character is forced to its platen in the operation' of the type writer, billing machine or other machine to which the plate 48 is attached. lVhen an electric current is available on the conductors to, through and from the coils 5, 6, and a determined type character is in its matrix, said character is held firmly in place, by magnetism, and at the same time a plate 48 placed on table 46, with pins 47 in apertures 48a, is held firmly in place by coil 6, pedal 38 and lever 29 being in substantially the position illustrated in Fig. 1. When said current is not available, either temporarily or permanently, corresponding matrix, the type bar turned so that the free end thereof is between the side members of the type character, and the lever or arm 8 is brought forward to rest on the bar, where it is yieldingly held by spring 10; thus holding said bar and character in proper relation while being soldered together. To solder the bar and the character together the arm 16 is brought downward on itsfuL- a type character is placed in acrum 17 until the forked ends 21, 22, of the lease pin26 from the aperture 25 with which A it is in engagement, and at the same time bar 35 is turned out of engagement with contact point 34 and the electric circuit is thereby The disk or table 14 is then turned on ball bearing 15 to bring the next one of the apertures 25in proper relation with pin 26, a suitable type character is placed in the matrix thereof, a corresponding type bar is turned into proper relation with said type character, and pedal 32 and lever 29 released. The soldering of said type character and bar, as above described, is afiected. The operation is repeated until all the type characters I to be used on the type writer or other like inachine are soldered to corresponding type ars. 1

When plate 48 is mounted on a type writer, billing or bars are turnable around a pivot, or a pivotal axis, to bring the type characters against paper on a platen, to obtain imprints fdrming a printed line. The spaced and angular relation of each of the type characters to the pivotal axis of its type bar at the time the soldering is effected must be accurately determined to obtain such perfect alignment and such exact spacing between the several other like machine, the several type characters forming a word or words on the line that the eye of an observer will not detect a variation in said alignment and spacing. Also, each character must be in a plane at right angles to the line of imprints obtained, or it can be detected and will mar the appearance of said line.

In some type writer, billing and other like machines, an aperture in the type bar adjacent to one end thereof has inserted therein a pin or wire forming the pivot around which said bar is turned in the operation of the machine, and the axial line of said pivot is the pivotal axis of the bar. In other of said machines a rigid member on the frame of the machine, which may be a wire, enters a recess adjacent to one end of the bar and extending inwards from one edge of the bar to a point forming the pivotal axis thereof, and the bar turns around said rigid member. In other machines the tvpe bars are mounted on ball bearings. the balls travelling in substantially vertical planes around the pivotal axis of the bar. The manner of mounting the units obtained by joining the type characters and the type bars in a tvpe writer or other machine forms no part of this invention: the obiect of this machine being to obtain means whereby each type character required may be joined to a selected tvpe bar in a determined spaced and angular relation to the pivotal axis of the bar, and with the type character so positioned on the type bar that an even spacing is obtained between all adjacent imprints in a line of said imprints.

The foregoing being the object of appli cants invention, each and every type character must be in spaced relation to the pivotal axis of its type bar, and each type character must be at a different angular relation to the pivotal axis of its type bar than each of the remaining characters is to the pivotal axis of its type bar. And further. each type character must be in a given osition in the plane in which the face, of the character extends, and it must stand on its feet in said plane.

The movement of a platen of a tvpe writer or other like machine. when the tvpe characters make imprints at a determined common center. and when said characters are at right ang es to the line of movement of said platen, causes succeeding imprints to he at the side of. parallel with and in proper sp ced relation to a preceding imprint.
